A sinking boat motivated me: long ago.
So me & Hugh invented the "ONETONPUMP"for hand cranking or pedalling.
Soon the design will be "out-there" for you to copy & make your own::
Then we can have "Pedal-Pump~Regattas"
At present ~ ~ I claim to have an axial-flow-turbine, with the most flow @ 1m 2m for 1minute sprint & 1 hour endurance : one & two operators.
Any challenges?

love to have you write an article about your pump for Human Power, it's been a long time coming, do you have any pictures to share??
glad to see you are still at it!

Progress has happened & I went back to basics :: the new model is dismantled again, the paint is drying & it will work soon. Yeah/but other missions happen ~ gotta go! When i get back I will video this thing. I've been at this a while & it works exceptionally well, it's new & every aspect of a design needs re-considering then testing to destruction.
So I hope to get a mob of pedallers to work it hard & see where it breaks.
Testing is next for performance ~ the numbers!
Well it just happens that I've been helping a student do a thesis on a 4 desimeter axial turbine ::
In particular we have been scrutinising the diffuser & stator to optimise velocity energy recovery :: spinning molecules around with twisted foils flying in annular flow passages::
when that is done maybe we'll test the OTP & redesign it / render it with 3-D CAD, get the CFD to tweak a few bits :: then this design can go.
Tell-me, what I want is a minimum of junk discarded in theis World, with "my Name" on it :: how does that happen? Pumps have a hard-life in corrosive/abrasive wet/muddy salty places,chucked around & neglected till needed. The R&D process is prototype make / test / evolve / discard. So I want to develope it before putting it out there.
Strategy is to peak the performance, make variants of the structure & mechanics ,pay attention to standardization ~ BIKE PARTS ~ common bits for ready maintenance.
So I've just been to a uni lab researching & can see the possabilities for students to take the idea ' adapt it to their requirements & resources :: before the makers get busy.
"GLOBAL STUDENT CHALLENGE" To make the best performer sprint // endurance 1,2,3m LIFT & the functional features ~ so we can compare towards ~
Making good ones that last 400 years [ non-biodegradable ] intuitive , adaptable , RELIABLE ,
PERFORM ~ pushing pedals is ultimately exhausting ~ This pump will get more overboard ~ before you are exhausted ~ sink?
There's lots to do & money to spend :: plans abound, progress is slower than it could be, help is on her way!
Mean-time THE SECRET is the angle-grinder gearbox ; with a cluster of sprockets, where the disc was,
A 12 cm impeller on an extention to the motor-shaft & & and the BIG-CHAINWHEEL now 80 teeth [Greenspeed-recumbent], maybe 100 next?
It's the sizes & shape of the water-passages ~ to guide it in to the ring, where the impeller gives it lift ~ then diffuse the velocity in expanding sections ~ molecular-momentum becomes pressure with flow == LIFTING WATER == that is a pump's only TRICK !
This one performs much better than what I had hoped. It is very effective for moving water @ LOW-LIFT.
If - only I'd had it in that sinking-sloop so long ago well ?OK a tool, equipment that may become common soon ~ speed to market ~ might make more junk, like I said, but slow to market with a webinar to share ideas ~ think about it ~ for a durable product ~ top design ~ usable #
But I don't have gear & skills to post a photo, however , with that bit of help from a friend ~
Soon- the video - stills - more of this chatter ~ next
"THE MOLECULAR VIEW OF A JOURNEY IN A TURBINE"

There is more ~ secrets of a pedal power fluid drive ~
A problem is in going 0ver-centre TDC & BDC the cranks align with the leg & torque is small.
Cranks horizontal for mex-leverage :: two operators cranks ~ out of sync ~ 90* degrees |_.
The V-8 effect, take turns for a power push on a pedal ~ crank ~ crank - this effect makes it more ergonomic // effective ~ a more natural effort ~ extending endurance of STAMINA.
It's yet to be tried : I mean the machine spins beautifully but apart from a quick splash : i havn't given it a workout.
I'm trying to rescue "onetonpump.com" from the sleaze invasion &
more of the "MYSTERIES OF PUMP" & "WHAT THE MOLECULE DID"
Later ~ keep on guessing?

Human Power will be more in evidence as fuel deminishes, becomes expensive in the transition to sustainably renewable.Food is the fuel ~ then. Pedal~power is the highest rate of power output a person can maintain. It's the mechanical interface ~ function & efficiency ~ that I am working on ::
Near Botany Bay. So I'm planning an inaugural meeting of "THE BUCKMINSTER FULLER READERS CLUB" for those interested & knowledgeable of H/P pumping in this studio/shed.

For the Forum~~~~~~Pedal-Powered-Boats
Ideal for canoes & dinghies ; catermarans ~ even better!
This mechanism I've described :: BIG CHAIN WHEEL + cluster on an a/g gearbox :: will do jus sweet for a boat.
I have an early model "Jet-ski" the stand-up & hold the handle-bar on an arm kind ~~ gutted it ~ now just a bit of 'surgery & skin-grafting"
Then pedals on tracks up-front :: with the chain-wheel on the starboard-side ~ ~ so the chain goes behind the captain ~ to the cluster ~ with a shaft across to the gearbox centrally mounted just above the waterline ~ propshaft goes through the transon with a water-seal [-::-]
Uni~joint to a "LONG---TAIL" with a LH Prop on the end -=- supported in a tube with a bearing outboard+thrust//bearing at the top & provision for elevating it to clear the water ; as you beach your vessel also steer with the "LONG---TAIL".
OK so that's 'in the pipeline' == I've got the gear ~ jus gotta "Put-it-together"
More watery doings ~ after my next job ~ a haulout for a 15m 20 ton lump of boat, heavy with barnacles ~ a different journey
Meantime ~ PP Pump is assembling ~ not yet wet!
The paint still is.

"Light-Bulb" moments occur ~ improvements happen ~ I'm still cutting metal & painting. It's all a pattern & proportion :: so I chop & change getting to the "perfect proportion" 1.618 [Pyramidal\/triangulation]
Designing & making a prototype is 'charting unknown areas' the inventor thing ! The good thing is it works excellently already & current modifications will 'up the ante' by heaps !
I mean I scour all sources / links looking for something like it #
Yes/but if you have seen an effective PP-Pump for low-lift // high volume ~ send the link.
I think I'm the one with the best machine , so the CHALLENGE stays.
Meantime I expect to be operating next year early ~ Someone who understands these things will visit ~ the team grows & I need help, if the idea grows , spreads as I predict.
Some uses
Lifting rain-water from a drain to a tank
By necessity as the tide rises /\ make a bund & pump it dry.
Pedal pumped cleaning of turbid water, by screen // membrane // sand-bed.Water runs down ~ particles are detained.
It can occur
onetonpump.com is happening with a quiet beginning ~ Desiderata !
To get you in a :MOOD: fer consideration
I have a lot of this obscure info to impart:: it's a niche // backwater of peoples' interest = nobody knows nuthin much who I"ve met lately [except one]

Hey Tony,
keep working on that pump!
I believe in making a prototype, and testing (playing with) the thing. usually I break it and that's good, shows where things need improvement.
often the first prototype is modified until it is to klugie to go on, then discarded in favor of prototype #2.
So... build it and have fun, you will learn more than if you draw the thing over and over.
pictures, we want pictures!!!
Merry Christmas

Still cutting metal & brushing on paint.
The demo I'm making has OTP with 2 pedallers lifting 2m to a 'baloon'/funnel inlet to the penstock, so a simple view shows shows an energy cycle & 'feet-on' gives a fluid-drive feeling, varied by changing the head & flow.
I have 2 impellers -~ high-pitch // higher flow ~ harder work.
low pitch ~ lower flow ~ lower torque input required //so higher lift @ more RPM.
Gearing is 80t chain-wheel to 3.3 gearbox via sprockets [13 ~> 18 ]
Ratio 80/13 X 3.3 = 20 :: 1 or 80/18 X 3.3 = 15 :: 1
Experementation will tell ; sofar it's within range of the optimum.
"The duty point" or "best Efficiency Point" is where it works best .
More litres water lifted per litre of sweat
The video is a-makin!

I'm off course again;; crossing 'the wide brown land' to Wagga Wagga, sat beside the Murrumbidgee River, before a return to Botany Bay & more to do before completing this part of 'ONETONPUMP & HEG / micro, but don't go away ~~ it'll happen. Soon I must go bush again ~ after that!

The new one works three times as well as the first,this week has been the first try ~ no probs !
The 'crew' is growing ~ another "Pumpologist"is joining. What about you? Do you know anything & have some understanding of this obscure niche in the "Techno-sphere"
An International, probably Global product is in the making :: presently in the "Concept-Proven" product evoloution / testing /improving the BEP /"try & break it" stage

It WORKS ,
I worked it with two people already,feels different pedalling 'out-of-synct! Strangely SERENDIPITOUS help is happening to get oveer the 'stall-point' TDC & BDC , sharing the load alternately.
Keep on quessing ?? More to come ~ out ~ of ~ obscurity ~
I'm learning also , error & trial & try again.
Now I start to make another 'new-model' transparent one =
then you''ll see @ glance & understand immediately, if not sooner !

"Fiddle~De~Dee" in de lab/studio/workplace. Now I'm putting on some more 'finishing-touches':: It's never ending the detail to attend to, so as to make a credible presentation to YOU my peers!
I've got the pump in a bath ~ lifting 2m ~ 90 degree bend [with LED inside] ~ trumpet discharge ~ drops into a reservoir [a circle of transparent vynl 'pleated' to a bike wheel rim & banded.] ~ into the penstock [a transparent pipe from the bottom of the vynl 'bag'] ~ through the HEG turbine [spinning the propellleeerrr] ~ back in the bath all bubbely ~ through the filter // seive [to remove bubbles & stuff] ~ past the straightening vanes ` up the inlet to the ring with those flying 'twisted foils' spinning circularly in an annulus ~ to the diffuser [recovering high-velocity energy to slower flow @ higher pressure] ~ out the discharge ~ up the transparent LED illuminated pipe ~ around & round the circuit is closed![What the molecule did all day]
YOU get the picture OK?
It's a long-haul to explain this; hang-in-there; if you ever get the feets-on feeling of this thing YOU'LL be surprized; first @ the quantity of that slippery liquid you can move; then the :ASSISTED-PEDALLING" is a 'strange-sensation'.Makes what was awkward more INTUITIVE :: two people co-operating, helping each other ~~ taking turns for the power-push-pedal
So YOU get the CLUE you HPV or Human Power Producers HPP; this is the "V-8 effect" ~~ smooths the "Torque-Trace" ie a peakey wavy curve is flattened @ a higher value ~ no more 'flat-spot' @ TDC/BDC.
The result is two people produce three times as much as one !!!
The torque requirement of a pump is constant [as with an elec-gen]; so any variations let the pressure/flow drop; which then requires accellerating = wasted effort.
Effort is the word, pushing pedals uphill ~~ how-steep // the choice is yours ~~ you can change ratios with this pump also impellers. It's a clear measure of STRENGTH & STAMINA.
For me , here at the proto-stage well I'm looking to reduce friction mech & hydro :: because efficient as it is it can be more & I resent wasting effort/energy for unwanted drag!
But a chance for me to show the WORLD an EFFECTIVE WATER MOVER.
More to do~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Anyway has anyone seen a better one [low lift HPP ]???

Hey Tony!
Sounds like some real progress, we would love to see some pictures or even rough sketches.
help us out, your ideas could save labor for many people. (not just those lucky enough to be in a boat taking on water!)


many thanks
keep up the good work

Well, I'm a mariner & it's that sinking boat got me going, from there I see it's use 'after the tsunami' cclearing those ponds :: as a filter lifter, cleaning water with mesh/membrane & sand-bed :: for fun a pp poolside water--slide [& pool sucker] :: in gymnasiums ,huffing~puffing[variable head//flow{{load}}measurable-parameters] with the energy stored or used for 'water~tricks':: in rice padis day& night with sun/rain shades music light & a group o people to share the load :: bumpingalong walking tracks site to site, hanging suspended in voids of vessels, under trees or bridges on ropes :: basement water remover :: gutter harvester :: hydroponics :: aquaculture :: thickening ice for skating or helo spots :: water heating ~ part of solar/evapourative desal :: yes! lots of uses ~ but remember 2m lift only ~ enough for lots ~ not high enough for more :: however the OTP is a "tool" for people to use, it's only a machine to give you an opportunity for shifting water effectively without [or with] the ic motor or elec, just oil the chain & bearings + maintenance..
Here & now by Botany Bay the plot unfolds! WATER &ENERGY I'm making a gadjet/demo-rig so people will feel ~ understand ~ enjoy ~ respect & love the viscous fleid +so critical to our survival+ this demo is an essential educational aid?
So more plot is to post the design to various Unis & hydro research institutes, let them evolve it to suit their needs & resources.
The CHALLENGE stands "Who can make the best performer?"
Line-up & show us your stuff!!
This can be made by "Shedsters" with enough ability ~ I'll show you later ,when the 3-D rendered CAD is on Linux/opensource or?
But meantime back to a drawing board, while waiting for some help!~

More details ~ seeking the 'glitches' :: although it's basically simple // a chain-drive to a gearbox to the pump~shaft :: makes the foils spin & lift de water up a pipe. This is a first-of-a-kind & I'm still 'tarting it up' for the photo to show you. Meantime Model # 13 parts got taken to get machined ~ then I get the 'perfect ratio' like 1.618 ! The performance will improve ; I know, getting an understanding is how progress happens ~ so the design evolves,,all the better for you [the potential user of it] The creative process for me is to remake each part, as I'm dfoing now with the 'BIG-chainwheel' & the pump-support-cantilever-trunion/fork ~ chain tensioner ~ beam!
This time of welded rhs & strip, easy when you have 'a tame welder' as I do ~{{FATE decrees many circumstances}}
DESTINY blessed me ~ our paths crossed [Thanks to Alex] ~ we worked in a hydraulics lab for 1/2 last year, soon we 'tune up the little turbine, make it perform even more efficiently ~ unveiling the mysteries of diffusers + stators.

Action happened : NOW the 100TooTh chain-wheel is in place.
Just gotta file the tips o the freshly machined teeth; I startrd with an industrial sproket, which had to be trimmrd to bike chain thickness & bored to 1.45 des [desimeters] sitting on the remains of ground off teeth of mid-chain-wheel-bolted 4 X 6mm c/s :: outside diameter .4m :
slightly larger than the cranks, the small chain-wheel is used to connect the other "Worker"[this is work as you may find out ~ ~ water is heavy stuff 1000 litres ~ a ~ ton.]
Soon I'll get a test going; the manometer is being made ~ this is a 2 1/2m measure on a float [so zero is automatic] ~ a hose-pipe from the discharge-pipe gives delivery head = easy to read.
An integrating flow-meter is needed,or a one-ton-tank.
The pictures are in a cameraa, but the computer can't handle them.
The video-girl has promised to visit ~ when it's all going.
Meantime it's raining : the river is rising, my kayak aready, I gotta go bush ::laugh with the Kookaburras :: it's a search for inspiration again.
I got a dose of that last week seeing the 16 y/o girl in a pink boat sail-around-the-world-then back into this special harbour ~ WQW
& it's for those adventurers this little manually operated bilge-water-remover [save you from sinking?] is initially intended.
!OK where is that file 'dentistry' on them teeth!
Do something more than bashing a keyboard!

OOps it's decimeters [ dec. for short ]
The BIG-chainwheel is 4 dec. diameter.
Lesson #1 old stretched chain gets shucked from big-chainwheel.
Remedy ~ @ the bike shop!
Lesson #2 alignment is important.
The pump is infront of the unit, so you can see what's happening with the machinery et al : this means the lower chain is in tension; the top slack. NOW ~ I don't want to use a derailleur [more friction] ~ so the tension & alignment gottabe good. Design features have that sorted::
The pump could be behind, like where rhe back-wheel of a bike is, but as this is for understanding, it's there to be seen.
Plenty rain just now running down the gutter into the Bay of Botany, soon as I have this thing going, I'm gonna stop the flow with a tarp over a timber beam to make a pond 1 or 2 dec deep :: upstream another beam with a seive / net / filter even chicken wire to stop some junk from blocking the inlet. Two guys pedal to push water up into a plastic pool on the verge. Then that water is all mine to use later after the pump has circulated it through more filter membrane // sand-bed // treatment.
Yes this tool will let you grab water ; clean it too : the heg lets you get energy out also.
Time to take the kayak & slide the slippery slope along the running river. It's how I know why water moves && I know even more from the turbulent pummelling & streamlined slides, I got in the big breakers of Sydney's surf, as a body-surfer ~ before the Ockenouie-Boards came & took the best breaks!

Today for the first time, 2 guys pedaled, while the video rolled, so soon the pictures can happen.[I havn't got the gear]
There were no probblems in that short run.
Now more attention to detail, while I strategize with what to do next,like get the CAD/CFD picture ~~ "anybody out there ??"[in Sydney ?]
Then the way to make it will be clear & as I see things ~ it's a simple machine ~ operating in a tricky medium & circumstances ~ requiring modest tecno skills. But only certain people are savvy to the water//machine mix, like the landlubber//seafarer ~ ~ worlds apart.
However anyone looking at this demo creation will see that it moves water up then ; then drops it for energy extraction & conversion to AC/DC then LED light. Simple, yet elegantly exposed!
No doubt it's been done before;but I havn't seen it; the out-of-phase-pedal-cranks |-- make all the difference when trying to push a constant~torque~load; sharing the power-stroke-sequence; of course the design can be expanded to get a real "V-8 effect" ,with even more 'cranky people'.
We will see as I'm sure this thing will have plenty of application to meet many needs.
The 100T chainwheel could be larger; I'm still using #14T on the cluster, so thats next.
Meantime proto #1 of this variant shure runs sweetly.!

Picctures are still coming, mainly because I havn't finished it,so now to strip it bare & weld a few tabs & lashing-loops & fiddely-bits: so that things can be attatched.#
It can be suspended, therefore pulleys shackel on & cleats to tie off.
Standing on legs in water a meter or more deep,nearshore, it'll be like an island or boat & if it's going to be worked a long time, the operators will need 'creature comforts' ~~ drink / food / music / stuff? / lectern for reading:laptop:DVD:writing. Boxes, bags, nets to contain all these ++ a toolbox with SPARE SHEAR PINS & impellers # chain / lube.Awning,wind protection = tent over, easily done!
Any way it's been worked a bit & the ratiois are spot~on & the 14/18 cluster of sprockets is the one.
Currently running on 16 T for the steep impeller with 1.5m lift is long-time sustainable for a couple of fit guys.Plenty of water on the move.
The test-rig is a-planning, flow measurement is a trick requiring :: meters, weirs, orifice-plates,weighing-tank, timing into a known volume.
Power Is torque by RPM.Measure RPM optically or magnetic p/u both chainwheel & impeller. Pump performance is best tested with a variable-speed pm elec motet vertically mounted on a 'free to turn' base restrained by a 'torque-arm' from which the leverage of the torque is measured & hence the power!
A family of curves, showing the performance @ various RPM will reveal all & of course you can get it as an App?[someday]
Anyway it's a cool day in midwinter Sydney, so strip it to the frame & start welding: maybe another week & it'll be ready to go "on the road"
Yeah? do you remember Jack Kerouak ? He wrote the book, long ago:: I read it & since then far pavillions I have seen & how they lift water in primitive places ;this machine will make life easier for some by giving a greater flow [efficiency] for the same effort @LOW LIFT.
My worry is;erosion on wet banks, unsustainable depletion of water-sources & making 'sushi' of fingerlings.& junk.
This machine is heading for difficult places from muddy dykes to stormy seas, continuous use to long-term dormant stand-by 'emergency-use'only. Reliability / ruggedization / repairability / intuitiv understanding # it is all in the design & making : of course it will evolve ~ but before "the cat gets out of the bag" I want to get it versitile,to adapt to circumstances in gymnasia, after-the-tsunami,Katrina,rice~padi,bilge,hydroponics ;swimpool PP-waterslide & cleaning.harvesting/storing/activating.
With this new device I'm going to do the "Pump-Circus" "On the Road" to showing people how to move water [@ LOW LIFT], have a new experience of the "feet-on feeling" for hydrodynamics, while marvelling at the largesse of flow :: learning to appreciate the wonders of water.Exercize / entertainment / educational.
So weld it paint it attatch bits & boxes & bags + wheels : then out of here heading for water to lift, the nearest is right outside in the street gutter
With a length of timber a sheet of plastic I can dam the gutter 2 dec. deep, with a filter mesh / screen upstream to block detritus getting washed away. Then pump it into whatever holds it & I have various plastic pools.
The street here floods on the top spring tides,I've seen it 1/2m deep with low atmospheric pressure to help, so I'm acutely aware & observant of the sea-level. Water is coming to get me! Mind you, I'm 3 floors up, by the lagoon north of Botany Bay, a good place to be if a 'medium' tsunami happens,[when NZ shakes]
Enough waffle ~ on with the job.
Drop in if your passing near Sydney Airport.
Help is needed in all respects.

It's a puzzle, a picture with many facets, some are missing, I may have found one yesty [Oz for yesterday]:: with skills for making a virtual rendition of this = 3-D CAD,++CFD. All you need to know will be revealed.
For his benefit [as we only had an intro-talk]: I explain.
This is a machine using pedal-power to rotate an axial-flow turbine.
Two operators work cranks 90* out-of-phase; turning 100T chainwheel to 14/18 cluster on 3.3::1 [angle-grinder] gearbox [spiral-bevel]; to a 12 cm impeller.
The operators have seats & handlebars on a 35x35mm rhs beam & the cranks-axles on a beam below; sortof like a bike built for two!
At each end is a staggered X-FRAME,rhs crossed at the top & a tie bar across the bottom, so the beams weld on these to make like a big "saw-horse".telescoping legs slide down inside the X lifting the frame for deep-water [a metre or more].
An extension out front supports the pump which is trunnion-mounted in a yoke or fork on a bar/cantilever, telescoping from a rod attatched near the crank-axle // pulled outwards by a chain/turnbuckle to tension the chain!
Critical feature is within the yoke A 'thruster' 1/3 of a circle of 4mm Al sheet to push into the groove of the a/g g/b so the chain-tension thrust is taken directly to the bearing/housing & not transmitted through the body.
A word of praise for the extrordinary resource the mighty angle-grinder, plentiful 'usually free', it's the motor usually fails leaving a well 'run-in' pair of gears most ratios are a bit over 3::1
This thing is amazingly rugged - except those steeel ball bearings better be cared for; water=corrosion. Chop the windings off the armature, make an adapter for a bunch of cluster ,where the disc was.
The pump hangs on the trunnion, with a limited freedom to swing X-Y.
Z is hanging on a link-shain, with a turnbuckle, a simple / cheap / reliable / intuitive adjuster.
The pump-case is fiberglass, ie plastic which distorts under load; so the discharge-pipe must be seperately supported with a flex-connect, as a pipe full of water is a heavy thing.
So this requires a crane-jib to support the end:: with two stays + turnbuckle moves the end XYZ, it's all done by using a wheel-castor with the wheel replaced by the seat-locking-collar from a bike with a tube sliding up-down+rotate+pivot :: adjustable.
I use inner-tube & hose-clamps for the flex section- very good.
By lashing one of those table-mats made of bamboo-strips tied together around the balooning tube a smmoother flow-passage is formed!
It's about sssooothing the flow passages for min friction & transitions. All the ENERGY goes in @ impeller::all else is LOSS.
Except the water now has POTENTIAL ENERGY STORED in it's elevated position.
Another jib can be rigged to hold the top of the disch-pipe.Cross-beams on the frame provide rigging for stays XYZ.
The frame has 8 cross-beams to make decks & lateral support/ steps.
I have a 5m catamaran, so this can be held between the hulls as a mobile floating pump, suitable for starting those big-siphons in irrrigation zones.
The frenzy of welding about to happen, like the fit-out of a boat's bare hull, umbrellas/ masts/ floatation/ tool-box/water-tank/lunch-box/what have I missed?
Zap-Zap!

"Bells & whistles"
A time with Nic the Welder; got lashing-points,for ropes/shakles/hooks;tabs for decks to be screwed to;tangs for rigging [stiffening]/foot-pads for plywood attatchment/sockets for wheels & the hpivot-point @ the heel of the jib, crane.Lot's of bits of metal zapped!
Back here cartop:grind/drill/wirebrush:: shape that steel!
Now it's out in the rain; shiny metal soon to rust, makes better key tu paint.Then make more bits for the bins/boxes/bags/nets/decks/masts.
Yeah well, I can say I'm a sailor & this rig is like an island or a boat and floatable :: so you need all the self-preservation stuff like drinks & foods//spares & tools.A lectern for a book pc screen, a table on which to do things, while you pedal the day away~~~~~~pushing water.~ A chart table, of course to navigate this concept to those who need it ~ by instinct!
Tomorrow from wet-rain to wet-paint.
Splash.
Oh that "Tour De France." _ what those guys could do with this ??

Massive fetish with a file,~ smoothing:~ this has got to be tactile, as to work with it;;hauling it,handling,climbing on,caressing or kicking it # YX=I=X/ is the keyboard rendition of its scheme~ you''ll see eventually.
The frame is 2.8m long 70cm wide 1.1 high, feels like 40 kg.
Anyway the paint is sticky:: very satisfying progress.
So what do you think?
Do you see the point?
It's a message for this time.

40Kg. exactly, with undercoat on.
To make it tactilic-smooth ~ wait till paint 90% dry :: then polish with a rag / the high-spots & dribbles are still soft to rub off: poor-adhesion is apparent, so those bits come off, otherwise, it would flake-off soon/later. Practical hints.
The RHS [rolled-hollow-section] 35mmm sq X 1.6 wall thickness, has ripples / bumps / dags /& welding intrusion inside ::= so next I've got to make the tool to do this ~ broach it ! ######\ Then the TELESCOPICS can function & this thing like a saw-horse - the A-A each end of overlapping rhs; so the legs slide up-dn // \\ adapting to uneven surfaces + standing in water. A projection bout .4m to hold the pump & provide rigging points for the two crane-jibs which hold the delivery-pipe &
17 lashing-points have just been added @ ends of tubes ~~ think "spider-web"; if you are down a bank or hole, get a rope +pulley & snap. The winch is on the "Wish-List"~I'm gunner put one or two on, so it can 'self-elevate' on one or two lines()
A "PIN-RAIL" is essential.
I have made provision for THREE-MASTS [being a 'schooner-driver' by trade] like \=I=/ so extensions can hold the canopy/tent/disguise
or sails to move across the water or land on wheels [sockets just added]
On the way to Nic's I tried it in Hobie-Cat #5m, did'nt fit, so back to the drg-brd for that one like the "BOAT-BILGER" is still a notion.
Make the deck NOW, cardboard template.

Yes I'm a mariner [ticket carrying] :: What comes naturally is setting up masts to fly sails. So this thing : X=O=I=O=X// :a tubular frame, based on a bike-for-two,has evolved.
Now, on the centreline is provision for 3-masts going up or they go down for support & stability.
The crossbars on the A-frame each end,can have axles to wheel it: also there are short vertical tubes [2cm inside] for socketing wheels to : also they swivel the heel o the pipe-crane-jib, on each corner.
Confused? All will be apparent, I've just got the gear to post pics=soon it will happen.
The decks are on,fore-mid-aft, 2-levels, pin-rails 10 fore 5 mid 9 aft belays. 2.5cm pins.
The purpose is to rig lines for a canopy [sun/rain/wind] up the masts :sails for propulsion over land or water ::leg/foot adjusters up-dn :: crane//jibs to support the discharge-pipe, with vertical+lateral rigging stays & guys!
,as a child I travelled 1/2 way around this globe in a "Liberty-Ship" a "three-island" freighter focastle-superstructure-aftercastle, with well-decks between, where the holds were, with the cranes over them : lines to winches animating the lot!The "Bosun" was my friend & protector, he showed me how it worked. Far away places & long ago!
How many ROADES do you have to go before you get it right?
Ah! Bob D; Good Question?
"Fair Dinkum" this "ONETONPUMP" machine is getting out of hand with all the extras-----however they do serve purposes. Provisions for versitile adaptation ,wherever & however lifting water.
Am I teasing you? Yeah a bit , I admit, due to my path in this life, I know about hydrodynamics & machinery plus rockin&rollin on the 7 seas; messing about with pumps; so I've conjouired-up this thing, I knew there was a better way for a human-body to use the muscles more effectively shifting slippery liquid fluids.
Even as I reveal this, now in 2010
,there is more, this is a crude beginning for a machine [with a purpose] the 'YG's"[young-gen[ of this world can re-invent it in so many ways; adapt to needs various.
The 3-D CAD man is talking,then you''l comprehend & be able to make your own.
Animated CFD is 'on the drawing-board'
Today, more preparations to get it "On the Road", out of here [upstairs] into some water & try to break it [find weak points]

If you ever want to make a frame=telescoping from RHS [rolled hollow section] remember to do quality-control first ** means check the inside is clear*** It's tedious with a file on a stick #######shredding steel.
Welding distorts & pulls it out of true.
I used what was free at hand, thinking I'll just make a "roughie" & a lot of effort has gone to fix the defects.
Nic 'The Welder' says use 2mm wall thickness on the 3.5cm;sq rhs, I used 1.6mm :: lighter of course but is it strong enough?
NOW---rigging the "leg-downhauls" //\\ +=finding the fair-leads over the top o the leg on a sheave, down to a pulley then to the hauler or belay.
Steel-surgery & a visit to a welder for mods!
Tomorrow- rig the derricks & learn their tricks;;
It is important to hold the pipe so that it puts no strain [forces] on the pump case ; so a flexible join is made of recycled inner=tube=hose-clamps.
This baloons when the pressure is up, which is amusing :: as it pulsates with a one-man-machine :: showing how the TDC<>BDC 'weak-point' [flat-spot] affects performance.
Decellerate^^^^^^Accelerate is a waste of energy~~~~~~~smoothoflowno interruptions~~~~~~~~~~~more litres & tonnes.
So that begat the \\X=OIO=X with the cranks 90* out of sync = + ||
The difference is massif, so I expect "PUMPERS" will shift more before exhaustion :: using a higher average torque~input.
The balooning tube can be streamlined by wrapping a "place-mat" made of strips like split-bamboo/cane & lashing it.
All the ENERGY is added @ the IMPELLER all else is LOSS ,by friction / viscosity / turbulence, or STORED POTENTIAL ENERGY & that's what I'm maximising : by minimising mechanical friction ::: NOW there are 16 BEARINGS + from pedal to impeller + 2 X roller=chain + 3 X chain-wheel + right-angle-spiral-bevel-gears 33#11 teeth ##
All with their own dragging-FRICTION you'll resent it , when you are exhausted.
The "art o PUMP DESIGN" means getting your head into the WATER PASSAGES :: where that bunch of slippery molecules must be contained , so guided accelerating via the INLET to the RING where the IMPELLER slices into the incompressible FLUID with a FOIL to 'fly' the LIQUID at maximum VELOCITY through this RING into the DIFFUSER where an expanding section lets those hurrying H2O molecules slow-down & get pressurised : while flowing on their way to the DISCHARGE.
~~~~~~~~~~~~~~~~~~SMOOTH STREAM LINES~~~~~~~~~~~~~~~~~~~~~~~~
This machine is made to extract your ENERGY, with a positive result of water where you want it.

DYMAXION is what BUCKMINSTER FULLER called it!
TRIANGULATION is everywhere on this self-elevating-frame; with two derricks.rigged to CHAIN**HOOK**TURNBUCKLE makes gross adjustment quick & fine tune easy.
Close to 20 turnbuckles already !!!!! What's he doing?
Lifting & lowering requires a 'gate' in the cross-beam of the front A-frame,for the roller-chain to pass throuigh. the first design failed, next one planned ~ when I get back from going to the bush tomorrow.Other issues preside!
This thing, as I work on it to enable the "TRICKS" that it must do to be versitile // adapt to many circumstances //have people on & around it // LIFT WATER :: it teaches me stuff :: serendipitously consequential to a basic concept."EUREKA" as you know who did say!
Added capabilities are built-in & reveal themselves as their need arises.
So I'm delighted & the performance of the thing is way over my origonal expectation. It's a good one.
Now go "WALKABOUT"
gone

BUSH WEEK !
You HPV guys, would be impressed, all these people getting around on ONE HORSEPOWER VEHICLES in this remote place known by "hidden" ~ "lost" ~ "forgotten" Valley ~ the "Endurance Ride" was happening::some start before dawn, ride long days up gullies ,over ridges, the idea is to not waste the horse ; so at the finish-line is a vet with stethascope, checking heartrate.
150 horses;50 dogs;people,trailers,4X4,tent/caravan camped all around where I was living in a bamboo patch; the sounds as for a bit the horses 'talked' with each other, then dogs,children,kookaburras, while a gale roared twice, punching us with willawaws, with a big moon.
Quiet nights. Change from the city. New ideas, look anew; see more mistakes to be fixed, before taking this out to show you pictorially.

Step by step, methodically; I made all decks,put it together, swung the derrick & it was obvious ~another lateral @ top front was needed for fixing guys to then the crane will be much more functional.Also lifting eyes // slinging points along the centreline.
Now stripped again,preparing for Nic the welder.
After that I'll get it wet soon after.
Past experience tells me to get it right first.In getting to this stage, I've had a few failures, like the first edition with tooth-belt drive & inadequately sized ~ broke when I wound it hard to impress potential makers. Embarrasing!
OH&S tells me to be careful & look for ways people can get hurt:this means -handgrabs footsteps,sharp edges giving the operator ways to climb all over, work the ropes, pedal the pump:the sstrength of this structure has to withstand,bouncing over rough terrain, dragging up slippery banks,swinging on ropes.
Pulleys on snaps, can easily be shifted between attatchment points all over,I just have to make them 'hard to break':: nothing is unbreakable. So the first mock-up heads for the bin, parts of it anyway.
Cutting steel again & drilling.
Oh! those horses, the sounds & sights linger:
